STAPLE-BINDING DELIVERY MECHANISM FOR PRINTING-MACHINES.

SPECIFICATION forming part of Late. Patent No. 510,842, dated December 12,1893.

Application filed August 15, 1893- Serial No. 483,192. (No model.) I i To all whom it may concern.-

Be it known that I, LUTHER O. CROWELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York,

have invented certain new and useful Im- I provements in Staple-Binding Delivery Mechanism for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates generally to that class of delivery mechanisms for printing machines in which the webs or sheets printed thereby are plicated and fastened together by I 5 means of staples set therein, in, on, or near, their binding line, and more specifically to staple inserting means that move or travel rotatively to and from the inserting point in the operation of carrying the staple into relazo tive position to the material forits insertion therein and co-operation with a clinching device, whereby high speed is attained, and the running material is bound together by staples without necessarily modifying its onward movement- The invention has for its object the completion of a book-like product by a continuous progressive onward movement of the material composing it, which material is print- 0 ed, plicated, and bound together by staplesset longitudinally therein or so that the head 3 5 proper lengths Without necessitating that the moving material shall be, even momentarilybrought to a state of rest from its entrance into, to its exit from, the machine, as is broadly set forth in my application, Serial 3 staple. Fig. 7 is a plan view, partly in section, 90

40 No. 464,007, filed February 26,1893.

The invention embraces the combination with means for plicating material in the sheet or web, and with one or more longitudinal folders, of staple inserting means rotating to and from the stapling point of the material,

in adifierent position.

seam that may be continuously formed without necessarily arresting or modifying the high speed at which the material may travel. onward from rotating mechanisms. Y

Modifications of the above and constructions I and combinations of mechanisms andvarious parts are also comprehended in this inven tion, all of which are hereinafter-fully ex: plained and pointed out in the claims.

Practical embodiments of this invention are shown in the accompanying drawings in which s Figures 1 and 2 conjointly exhibit an'end elevation as seen from its non gear side, of so much of the delivery mechanism of a web printing machine as is necessary to illustrate the present improvements, the same showing two longitudinal folders whereby sheets or webs of material, as paper, are plica'ted by doubling or folding the same longitudinally or in the direction of their onward travel, two disk like rotating carriers in which are mounted the stapling mechanisms, and combined cutting and folding cylinders which sever the stapled web transversely into sheet lengths and fold the latter. Fig. 3 is a side elevation of the same, the carrier which supports the staple forming, presenting and inserting mechanisms being shown in longitudinalvertical section, while the cams for imparting 86 motion thereto and their supporting brackets are shown in elevation. Fig. 4 is an elevation of the disk like carrier in which aremounted the staple forming, presenting and inserting mechanisms, portions being broken away to expose inner parts. Figs. 5 and 6 are similar views of parts ofsaid carrier, illustrating difierent positions of the mechanisms during the operations of forming and protruding a of said disk like carrier and its co-oper ative devices. Fig. Sis a facial elevation of said carrier,'sli owing more particularly the levers for operating the stapling mechanisms as well as their actuating cams. Fig. 9'is a partial view of the same, showing some of the parts Fig. 10 is a sectional elevation of a part of said carrier showing more particularly the wire guideway. Fig.

Fig. 12 is a side elevation of the upper portion of a longitudinal folder and arotative stapling mechanism having a disk like rotative carrier combined with the guiding roller over which the material is conveyed to such folder. Fig. 13 is a plan view of the same. Fig. 14 illustrates a detail of construction. Fig. 15 is a detached view of one of the fold laying rollers. Fig. 16 is a front elevation of the lower portion of a longitudinal folder, having combined with it a disk like rotative stapling mechanism. Fig.17 is a side elevation of the same as seen in the direction of the arrow 17 in Fig. 16. Figs. 18 and 19 are elevations, partly in section of the carrier supporting the staple forming and presenting tools in which modified constructions of these tools are illustrated. Figs. 20 and 21 are views of some of these tools detached, and illustrate their mode of operation. Figs. 22, 23, and 24, are perspective and sectional views of finished stapled products. In Fig. 22 is shown a single pack with a folded back or rear edge; in Fig. 23, two packs are shown each having folded back edges, and in Fig. 24, a single pack is shown as composed of a pack of leaves having free back edges.

The printing machine of which this staplin g mechanism is designed to form a portion of the delivery apparatus, may be of any of the many known types which will rapidly produce printed sheets and deliver the same in the condition of many plies suitably arranged to be bound together and made a finished product, as a pamphlet or newspaper, and such machine may have the material to be printed fed to it in the sheet or web form. Preferably, however, the printing machine will be adapted to print upon a web or webs of material and be provided with means for plicating the web or webs by associating or folding, and with means for transversely severing the plicated webs into sheets.

While the associating of webs or sheets from one or many printing machines, may be accomplished by angle bars or by rollers, the preferable means to be employed for plicating is longitudinal folders, of which two 49, 50, are shown, either one or both of which may be employed, and with or without slitters, as 58, and, when the two longitudinal folders are used, the webs which they plicate either by associating or folding are or may be again associated before they enter the stapling mechanism, as by the rollers 75, 76.

Thelongitudinal folders 4:9, herein shown, are of ordinary construction, such as is described in Patent No. 331,280, and each one may operate upon a single web or simultane' ously upon a multiplicity of webs, as the four webs marked P, L, I, G; A, T, E, D, and p11- cate the same by folding or by association. Each folded web or webs from each of the folders 19, 50, and the webs from both of said folders after being associated at the rollers 75,76,will, as they leave the external turners 67, 08 and 69, and pass between the fold laying rollers 71, 72 and 73, 74. (if the slitter is out of use) consist of twice as many plies as there are webs and this will continue to be the case when they are associated with each other at the rollers 75, 7 0, and, if the slitters 58 are active, the number of plies Will remain the same but each plication will become a separate sheet having a free instead of a doubled binding edge.

As is well known to those skilled in the art of printing the webs may be severed transversely into sheets before delivery, in which case ataped pathway must be provided to conduct the severed sheets onward until mechanisms are reached that form sheet conveyers.

In the machine shown, the web form is preferably maintained until after the stapling is performed, when the stapled Webs are directed to cutting cylinders 102, 103 to be cut into sheet lengths. These cylinders 102, 103 carry respectivelya cutting knife or blade 15, and a co-acting cutting groove or slot 17, by which the web or webs will be severed transversely along linesasheets distance apart and that the same cylinders may also impart afold to the sheets the cylinder 102 is or may be additionally provided with a double rotative folding blade 24, that co-acts with folding rollers, as 28, 29; and cylinder 102 should also be provided with sheet carrying pins 27 for controlling the material, all substantially as is shown and described with respect to the like cylinders or carriers referred to in my application, Serial No. 464,007, filed February 28, 1893.

The cylinders 102, 103 are geared together by toothed wheels, one 63 on the shaft of cylinder 103 only being shown, and the rotative carriers 100, 101 for the stapling mechanisms are mounted upon shafts that are likewise geared together by toothed wheels, only one 64 on the shaft of carrier 101 being shown, and the said wheels on the shaft of cylinder 103 and the shaft of carrier 101 are connected by an intermediate 65. Said parts thus run in unison and they will be geared with and driven from the main or printing ma chine so as to move concertedly with such of its parts over or between which the paper web or webs or sheets pass. The external turners 67, 68 and 69, 70 when in roller form, as shown, may be geared so as to be driven in unison with the other web guiding or carrying devices, as are the fold laying rollers 71, 72 and 73, 74 and the associating rollers 75, 76.

It will be understood that a web or webs or sheets caused to pass over the longitudinal folder 40 or 50, will be doubled or folded longitudinally, and that said fold will be pressed flat or laid smooth in passing between the fold laying rollers as 71, 72 or 73, 74, as is set forth in the said Patent No. 331,280; also that suitable lengths of such folded or plicated web or webs will be severed to constitute sheet lengths by the action of the cutting devices 15, 17, and that such sheet lengths will be carried by the pins 27 within the range of action of the rotative folding blade as 24, and be folded transversely thereby through the rollers 28, 29, as is set forth in said application, Serial No. 464,007; and it will be obvious that the said rotative folding blade may be omitted, if desired, and the longitudinally folded sheets be delivered, after the cutting devices have formed them, by any suitable mechanism.

Heretofore it has been customary to apply a line or lines of paste along the line of longitudinal fold, when it is the ultimate binding line, so that the plicated or folded product shall be bound as a book like product. Owing to the difiiculty of applying such lines of paste, and the iueiiicient union such a means of binding affords, it-has been found advantageous to accomplish this binding or union of the separate sheets by means of wire staples entered through and clinched upon the plies, parallel with, along, or in the binding line thereof.

To perform the operations of forming, presenting and inserting the staples while the web or webs or sheets are on the run so that said staples lie in or are aligned with said binding line, the carrier 101 is provided with novel mechanisms for forming and inserting the staples, and preferably a co-operating carrier 100 is provided with the coacting clinching device whereby the legs of the staples are clinched down upon the material. These carriers are disk like and thus bear on a narrow width of the material near to its binding edges, which may be .cut or folded edges, all of the plies of the material being pressed together in passing between the associating rollers 75, 76. This disk or carrier 101 is mounted in a fixed position upon the shaft 66 and is provided with a rim having cut into it, concentric with its periph cry, a wire guiding groove 11 in which is fed the wire 4 from which suitable lengths are to be cut to form the staples. This wire is fed into this groove 4 from a spool or reel by means of feeding rollers 51, 52 driven at a suitable speed, from which rollers said wire is entered through a stationary guide block 41 having a laterally bent channel 40. See Fig. 7. This guide block is supported by a bracket 42 and consists of two members between which is embraced a plate 53 the forward end of which has an inner edge parallel with the inner wall of the groove 11 and so curved that it enters into said groove and practically forms with said inner wall a continuation of the wire channel 40. See Fig. 10. The metal Web 0 of the carrier 101 has a part or quadrant like section removed to form an opening to accommodate the swinging movement of some of the'devices which are supported by an arm 43 fixedly secured to the carrier shaft 66, and which arm carries journal bearings for the rock shaft 44 that supports the levers carrying the .two arms 2, 3, of the staple holder or presenting tool and the staple driver 31, all of which levers are capable of independent movement either with or upon said shaft 44, as will presently appear.

The rim of the carrier A has a section removed to provide a recess that will accommodate the movements through it of the arms '2, 3 of the holder or presenting tool and the inserting tool or driver 31 and to provide for a lateral movement of the forming anvil 10, see Figs. 5 and 6, where the side of this opening is exposed. The forming anvil 10 is a block of metal having a length equal to the distance between the outsides of the two legs of the staple which is to be formed about it, a width about equal to that of the rim from its inner face to and inclusive of the position of the wire channel 11 therein, and a thickness equal to that of the carrier rim between its periphery and the outer wall of the wire channel 11, or as great as the length of the staple legs which are bent over it. It is securely attached at one side toacurved spring plate or support 30 that spans one side of the recess cut through the rim of the carrier,-see Figs. 4 and 9, which spring support 30 is provided with elongated holes by which it is fastened to the side of the rim by set screws, so that said block may move laterally. Thislateral movement is imparted to it and to the anvil 10 by means of curved enlargements 13, 14 on the arms 2, 3 which press the plate 30 sidewise and hence move the anvil correspondingly. Thus constructed and mounted the anvil 10 normally forms by its under or interior curved surface a continuation of the outer wall of said wire channel 11 that guides the wire, and its exterior surface forms a con tinuation of the periphery of the carrier. The arm 3 of the holder or presenting tool is carried by a lever 34 that is fast upon the shaft44, and the bending arm 2 is carried by a lever 33 that is pivoted on the shaft 44, and preferably connected therewith by a coiled spring 9 that is fast to and coiled about said shaft and has its free end bearing against the rear side of the lever 34, said lever being held in its appropriate relation to the lever 34 by the action of this spring constantly pressing it against a stop plate 8 attached to the lever 34, by which construction said arm 2 will be moved outward by said shaft concertedly with thelike movement of the arm 3, but may be moved inwardly independently of it. These arms 2, 3 have their inner faces or sides grooved to provide for the reception and guidance of the staple legs, and the extremity of the arm 3 is beveled or otherwise fashioned into a cutter as 20 which coacts with the edge 7 of the rim of the carrier at one end of the recess cut into said rim, the cutter 2O acting to sever the wire as it forces it against and past the edge 7. The shaft 44 is rocked to swing the bending arms 2, 3 in a direction ICO to protrude said arms without and return the upon the end of which travels in the path of a cam 32 fixed by brackets, as 47, to the framework. The inserting tool or driver 31 is carried by a lever 36 that turns upon the shaft 44, which lever 36 has a laterally extending rock arm 6 the stud or bowl upon which enters into the path of acam 23 fixed by brackets, as 45, to the frame work. This lever 36 has its free end bent inward to properly position the driver 31, see Fig. 9, and the sides of the latter are suitably shaped to enable them to play in the inner side grooves of the bending arms 2, 3, and it, like them, has a movement in a direction slightly tangential to the periphery of the carrier.

The normal position of the parts being as shown in Fig. 4, it will be apparent that the wire 1 from a supply reel or spool will, by a suitable rotation of the feed rollers 51, 52, be appropriately fed on ward into the channel 40, and being forced through this laterally bent channel in the guide block 41, will be carried into the circular wire groove 11 in the rim of the carrier and be held in said groove by the inner face of the guide plate 53. Thus entered and guided in the groove 11 the forward end of the wire 4 will be entered between the interior surface of the anvil 10 and the face of the inserting tool or driver 31 which latter may, if desired, have a groove in its face to aid in guiding and to securely hold the wire. As the interior surface of the anvil 10 forms a continuation of the outer wall of the groove 11, the path of cam 23 will be shaped so as to normally hold the face, or the groove therein, of the driver 31 in a position to form a continuation of the inner wall of said groove 11. As soon as the staple mechanisms have reached a proper position in their rotative travel, the driver 31 may, if desired, be slightly moved outward by a suitable shape of the cam 23 and thus gently clamp the wire against the under side of the anvil 10. Then the cam 32 will act upon the rock arm 35 and move the arms 2, 3, outward. The cutter 20 on the arm 3 will first bear against the wire 4 and forcing the same against the edge 7 of the rim of the carrier will sever the wire, thus detaching a length suitable for the formation of a staple. The ends and faces of the arms 2,3, will simultaueouslyor about so bear against those portions of the wire length that extend each side of the anvil 10 and operate to bend the same outwardly against the sides of said anvil, as in Fig. 5, thus forming outwardly extending legs which will lie in the grooves in the inner faces of arms 2, 3. When this is accomplished, the cam 23 causes the inserting tool or driver 31 to take up its outward movement and to advance concertedly with the arms 2, 3 of the holder or presenting tool. As the concerted outward movement of the driver 31 and the arms 2, 3 is made the cam like projections 13, 14 on the latter will press upon and laterally displace the anvil 10 by hearing against its retaining spring 30, thus permitting the crown of the staple, and the driver 31 behind it, to move past the anvil at one side thereof; and, to aid the speedy movement or lateral displacement of the anvil its inner side maybe slightly beveled, so that the staple will somewhat readily pass onto its side surface. \Vhen the staple has cleared the anvil the driver may be retracted, as the resilient action of the staple legs will hold the staple in place, and the spring seated anvil 10 may be pressed back to place and rest underneath the crown of the staple; but practically, since, for the setting of the staple, a setting bed stationary with respect to the holder arms is desirable, it is preferable, to have the cam 23 hold the driver 31 in its protruded position until the staple legs are clinched, and sometimes, it is desirable for it to have, and the cam 23 may be shaped to impart a very slight additional outward movement to the driver to aid in forcing the staple legs well home after they are bent down or while that operation is being finished.

Protruded in its position shown in Fig. 6 the staple will be within the embrace of the arms 2, 3, of the holderor presenting tool and practically stand on the periphery of the carrier with its legs standing tangentially therefrom and directed at the points in the material which they are to enter and toward the clinching groove or die 12 that is cutinto the periphery of the carrier 100 and by which they are to be clinched, in other words be properly presented in inserting position. This clinching groove 12 has its ends curved inward. so as to turn the staple legs inward or toward each other, and acts, as the carriers move onward concertedly with the plicated webs run ning between them to gradually bend said legs, as they are protruded through the webs and enter into said groove or die 12, while the staple is securely held in the arms of the holder or presenting tool with its crown then resting upon the driver 31, said groove finally acting to press the staple legs snugly down onto the webs as the point of nearest contact of the two carriers is passed,which is the time when the driver 31 may move slightly outward to aid such clinching.

As in my said application, Serial No. 464,007, the various described substitutes for the carrier 100 and this clinching groove therein may be used in connection with the other stapling mechanisms herein shown and described.

It will now be perceived that, in consequence of the distance of separation of the two arms 2, 3, of the hold er or presenting tool which act as sustaining supports for the staple legs while being set and clinched, it may not be practical to have them move rearwardly or retract in concert, and hence it is that the arm 2 which is the first one that has contact with the periphery of the carrier 100 or the clinching device, is not only made the shorter so that it may not move backward until after the staple leg it supports enters into the clinching groove or die 12, but is spring seated so that it may move backward without affecting the like movement of its companion arm 3. The arm 3 might also be independently spring seated so as to be pressed backward by its contact with the carrier or the clinching die, but since these arms 2, 3 must be positively withdrawn within the carrier 101 so as to repeat their operations of cutting the wire, bending the same into staple form, protruding, carrying, presenting and guiding the same for setting, it is preferable to perform the retraction of the arm 3 by means of the cam 32, and it is accordingly shaped to withdraw this arm 3 progressively so that said arm shall continue to just clear the face of the carrier 100 as it approaches and moves past it. All of the stapling devices will now make their rotative circuit and the wire 4: being continuously fed into the groove 11 of the carrier 101 the operations described will be repeated. The size of the carrier 101 circumferentially relative to the length of a sheet will of course determine the number of sets of stapling devices required to suitably fasten the plicated sheets together, and since two staples in each sheet ordinarily will suffice, the carrier is shown assupplied with two sets of stapling devices, the duplicate set being shown in dotted lines; but it must be understood that the number of stapling devices may be greater according to the bulk of the product, it being practical to make the circumference of the carrier 101 less and greater than the length of a sheet, in each case a suitable number of sets of stapling devices being used and the inward feed of the wire 4 timed accordingly. The webs folded longitudinally by either of the longitudinal folders 49, 5O will,as they pass between the stapling mechanisms constitute twice as many plies as there are webs. Thus two webs folded, say one from each folder, will produce four plies and they will be lapped together or associatedin passing the rollers 75, 76 and their doubled or binding edges will pass near to the'line of travel of the stapling mechanism and thus have the staples entered through said plies parallel with and near to said doubled edges. If, however, these longitudinal folders are provided with slitters, as the slitters 58, then said binding edges will consist of free leaves, as will be apparent. These slitters may be arranged so as to be put into and out of opera tion in any convenient manner, as by hanging them in sliding bearings as shown, and they may be placed so as to co-operate with the folder by running in contact with its face, or be mounted to operate in the rear or in advance of the folder.

While the foregoing description has referred chiefly to the use of this longitudinal stapling mechanism in connection with but one longitudinalfolder,it will appear from Fig. 1. that such a stapling mechanism may unite webs plicated by association or folding accomplished by a number of longitudinal folders,

.the product of each of which may be one as 58, are used, will determine the ultimate product which may vary considerably. If the webs are simply folded in passing over the longitudinal folders then the product will have a doubled or folded back or binding edge. Thus, as in Fig. 23, anumberof webs, say three from one of the folders, will produce a plicated pack of six leaves having a common fold. One or more webs from each of the folders, say two from each, will produce a pack consisting of two sections, each having a folded back, as in Fig. 24. 'If the webs are split longitudinally by a slitter, as they pass onto, along or from such longitudinal folders, then the product will consist of separate leaves or become a pack that has afree back or binding edge, as is shown in Fig. 24, where two webs from each of the longitudinal folders thus split are shown as constituting a product consisting of eight leaves.

The staple bound webs may be severed into sheet lengths and folded by cutting and folding mechanisms mounted in the carriers 100, 101 and be delivered therefrom as finished products, as is described and shown in said application, Serial No. 464,007. lf, however, it is preferable, to have the stapling mechanisms distinct and separate from the severing or tinalfolding devices, this may be provided for by leading or conveying the stapled webs to any suitable cutting, or cutting and folding mechanism, one example of which. is shown in Fig. 2, Where the cylinders 102, 103 are supplied with the requisite devices for severing the webs into sheets and folding the sheets irrespective of the stapling mechanism carriers. It should be stated, however, that the cutting mechanism must be properly related to the stapling devices so that each sheetnot only receives its appropriate number of staples but that they shall be set at the same points in each sheet. As an example, herein the carrier 101 is equal to the length of a sheet, say eighteen inches. Its stapling mechanisms are nine inches apart. Hence these staples must be four and one half inches from the top and bottom edges of each sheet, and the cutting mechanism must sever on this line. While this stapling mechanism is shown in connection with a longitudinal folder from which it receives the material to be stapled, and said longitudinal folder is designed to form a part of a printingmechanism whereby said web or webs are printed before delivery, it will be readily apparent that this stapling mechanism may be supplied with webs or sheets or packs of the same fed to it over a guiding table or otherwise entered within the range of action of its mechanisms, its capacity for stapling rapidly moving ma terial without retarding the same and thus perfectly spacing the distance between the staples, adaptingit for use as a means for stapling books and similar packages of sheets or signatures or articles requiring to be bound by means of a succession of staples.

Although I have shown in my application Serial No. 183,191, filed of even date herewith, a rotative stapling mechanism comprising devices which set the staples in lines parallel with the run of the material and have illustrated the same in connection with longitudinal folders, and have also devised other structures designed to make and set staples parallel with the run of the material, the structure of stapling mechanism herein shown has been selected by reason of its special adaptability therefor, as the embodiment of the broad invention of the combination with a longitudinal folder or folders of a stapling mechanism cooperating therewith to form, insert and clinch staples in material plicated by a longitudinal folder, so that said staples shall have their crowns lying parallel with the run of the paper.

In the mechanism thus far described, the said stapling mechanism is shown as separated from the said longitudinal folder. It is desirable, however, where a compact machine is required, to combine the stapling mechanism more intimately with the longitudinal folder. This may be accomplished either by placing said stapling mechanism in such a position as to operate upon the sheets, web or webs before the same pass onto the longitudinal folder, or directly upon the longitudinal folder so that the stapling mechanism may operate simultaneously With the longitudinal folder. These embodiments of the invention will now be particularly described in connection with Figs. 12 to 17.

The modified arrangement now about to be described will be considered to be applied to the longitudinal folder marked 50 in Fig. 1, as is indicated by the part marked 50 in these latter views, which, in Fig. 12, indicates the upper end of one of the sides of the said longitudinal folder and in Figs. 16 and 17 the lower end of the same; its external turners being marked 69, 70, and its fold laying rollers 73, 7* as before. As in this case there will be no staple mechanism carriers between the longitudinal folder and the delivery mechanism for the stapled web, the cutting folding delivering cylinders 102, 103 are, as is indicated in Fig. 16, situated directly beneath the longitudinal folder.

Considering now Figs. 12 and 13, we find that the web or webs from the printing machine, or other source of supply, pass over guiding rollers 79 and 80 and from the latter onto the longitudinal folder 50. In this construction, the said guiding roller 80 is provided with the clinching die 12 and there is arranged for conjoint action therewith a disk like carrier 10]. which is provided with staplin g mechanisms constructed to operate precisely as do those in the other figures illustrative of their construction. In this modification, however, the said disk like carrier 101 has its shaft 66 journaled in lever arms 81, 82, and is provided with a driving wheel 97 on one end of said shaft. These lever arms are fast upon a rock shaft 83 and the cams 23,32 for imparting movements to the stapling mechanisms, as well as the wire guide block 41 and its appurtenances are also fast to said arms.

In order that the stapling mechanism may be put out of and into operation, the rock shaft 83 is provided with a lever arm 84 whereby the parts may be lowered into the operative position shown in Fig. 12 and there be fixedly held by a rotative locking bolt 85 or be rocked so as to lift the disk 101 and its appurtenances out of operative relation to the guide roll 80 which carries the clinching die 12, at which time the parts will be fastened and held by the rotative locking bolt 86. The guiding roller 80 which is driven from some part of the printing machine as by beveled gears 90, 91, carries upon it at one end a pinion 92 that through an intermediate 93 en gages a wheel 94 that is fast upon and drives a short shaft 56 that is aligned with the shaft 83 upon which shaft 56 is carried a wheel 96 that meshes with the wheel 97 which latter imparts rotary motion to the shaft 66.

In order that the paperin web or sheet form may not be disturbed by the action of the stapling mechanisms upon it, propelling rollers are provided at each side of the disk 101; of these the propelling roller 88 is carried in arms 104, 105, hung on the shaft 83, and the propelling roller 89 is carried in arms 106, 107 that are hung in a sleeve 55 that turns on the shaft 56, which sleeve 55 is made fast to the shaft 83 by a brace loop 57; in which construction these propelling rollers will be swung out of or into operative relation with respect to the roll 80, as the carrier 101 is moved by the lever 84:.

hen the stapling mechanisms combined and arranged as just described are in operation, the sheets or webs passing over the roll 80 onto the longitudinal folder 5O wil1,as is obvious, be stapled longitudinally in their central or other line of folding which is to become the binding line thereof. This stapled line may be the line upon which the fold is imparted by the longitudinal folder that will be the ultimate binding line of the product made from said webs. If, for any reason, it should be found desirable, the act ual line of binding need not be the actual line of folding, but the stapling may be so performed that the staples will be close to or slightly at one side of the actual folding.

In Figs. 16 and 17, the shaft 66 of the stapling mechanism disk like carrier 101 has upon it a beveled wheel 108 that engages a similar wheel 109 on a shaft that is driven in unison with the other parts by means of a train of wheels 110, 111, 112, the latter meshing with the wheel 63 upon the shaft of carrier or cylinder 103. The rotating disk like carrier 100, which is provided with the clinching die 12, is arranged to protrude through the lower end'of the longitudinal folder for co-operation with the stapling mechanisms car= ried by the disk 101, and suitable rotary motion is imparted to it by means of a pinion 118 on its shaft that is driven by a train as 119, 120, 121, 122 from a like pinion 123 which is fast upon a short shaft that is provided with a beveled pinion 113 that is engaged by a like beveled pinion 114 whose shaft carries a wheel 115 driven through intermediates 116, 117 from the wheel upon the carrier or cylinder 102. In these views the cams 23, 32 and the wire guide 41 are supported from the le vers 81, 82 that are shown as secured rigidly to the frame work, but these levers may be made adjustable as in Figs. 12 and 13, so as to throw the stapling mechanisms into and out of operation as may be desired. I

In Fig. 17, there is shown a wire reel R for supplying the wire through the feeding rollers 51, 52 to the disk like carrier 101 and such or some equivalent arrangement of the reel will be made with relation to the said disk like carrier 101 in the various other arrangements shown.

In mechanism arranged as last described it will be obvious that the webs of paper passed over the longitudinal folder 50 will be stapled as last hereinbefore described. It may now be stated that the clinching die 12 instead of being carried by a rotative part may be made a fixed part, or in other words, formed in the face of the longitudinal folder 50 in like manner as has been described in my said application, Serial No. 464,007, with respect to the equivalent or other clinching devices.

The wire cutting and staple devices supported by the carrier 101 may be modified in many ways, some of which are illustrated in Figs. 18, 19, 20, and 21. Thus the cutting mechanism may be separate from the holder or tool and consists of a sickle like blade or rotary cutter 37 that is mounted upon a rotative shaft and oscillated at suitable intervals to sever a wire length in connection with the edge 7 of the recess through the periphery of the carrier 101. The arms 2, 3, of the holder or presenting tool may be mutually and rigidly attached to a lever 38 and that lever make timely oscillations through the action of a rock arm 39 anda suitable cam 130. So also the driver 31 may, while sliding in the interior staple guiding slots in the arms 2, 3, be spring seated upon a fixed seat 22, and have a guiding spindle that is tapped into the base of the driver 31 and provided with a head 19 hearing on the outer side of the carrier of the This construction of the devices will operate as follows:The wire fed onward, as before explained, between feed rollers 51, 52 and led into the groove 11 and there held by means of the bearer 99 will be fed forward suitably to furnish staple lengths of wire successively to the operating devices. When thecarrier 101 in its rotative movement brings the staple tools into proper position the rotativecutter 37 will be moved to sever a wire length. Simultaneously or about so, the lever 38-will be moved to press the arms 2, 3, outward, the

driver 31 being carried therewith and pressing the staple length of wire against the under side of the anvil 10. In their outward movement the arms 2, 3 will cause the ends of the wire to be bent outward against the sides of the anvil 10, as in Fig. 19, thus forming the staple about the anvil with its legs lying within the grooves in said arms 2, 3. In this position the arms 2, 3, and the staple they carry will be supported beyond the periphery of the carrier 101 to the fullest extent they reach and the driver 31 will have been suspended in its outward movement by contact with the anvil 10 so that it stands a suitable distance rearwardly of the ends of the arms 2, 3, its supporting spring being still compressed though elongated. When now the setting point for the staple is approached the staple legs will be directed toward the points of insertion as hereinbefore explained and the anvil 10 may then be withdrawn. As the periphery of the co-operating carrier 100 and the setting die 12 it supports are approached and passed, the lever 38 will be so gradually and timely moved as to withdraw the arms 2, 3 progressively within the carrier 101, as the staple is inserted in the material and its legs are gradually turned inward and clinched down upon the material. During this operation, the driver 31, maintains its position coincident with the periphery of the carrier 101 and through the action of its supporting spring affords an abutment conducing to the perfecting of the setting operation. As the anvil 10 is preferably wedge like at its end (see Fig. 20) it will be apparent that it may actas a constant support, while being progressively withdrawn laterally to insure the perfect setting of the staple. The setting operation being complete the tools are returned to the positions of Fig. 18, while carrier 101 continues its rotative movement to carry the tools to the wire length receiving point. The

anvil 10 having moved into its position to v have the staple formed about it, the cutter operates to sever the wire length and the movements described are repeated. By considering Fig. 21, it will be perceived that the arms 2, 3 are connected by side plates so as to form continuing sides to constitute the said arms a single instrumentality with a wire staple slot through it in which the driver 31 moves. The disk like carrier 101, its appurtenances and the co-operating staple leg clinching device, may be adjustable longitudinally in order to insert the line of staples more or less distant from the binding edge.

As sometimes either from the size of the wire, the numberof plies of material fastened or imperfect clinching of the legs the staple may protrude somewhat from the material, or in conjunction with the folded part of the material become too bulky, it is desirable that no obstruction to its ready passage through the fold laying rolls shall exist, and henceone or both of them are grooved, as at 16, see Fig. 15, to provide an enlarged space through which the stapled line may pass.

It is to be understood that the independent means referred to in the claims, are means additional to the staple holder or presenting tool and which are to feed plicated webs on sheets when the staple holder or presenting tool is not in the position where the staple is to be inserted into such webs or sheets.

It is to be observed from the foregoing description that the staple inserting means consists generally of a staple holder or presenting tool which holds or presents and sometimes guides the made staple so that its legs shall properly enter the material, and a tool or driver which acts to compel the entrance of the staple into the material. This staple inserting means moves rotatively from one point, where the wire length is received, to another point to which the holder or presenting tool carries the staple for insertion into the material, said tool in connection with the anvil operating, while traveling rotatively, to form the staple, and, in connection with the driver to move and protrude the staple into setting position with respect to thetools. The disk like carriers 100, 101, need not have continuous peripheries, so far as carrying the staple inserting and clinching means are concerned. Since a wire guide 11 is essential for directing the wire to the tools, it is preferable to provide it in said disk and hence to have it continuous; in the case of the disk 100, however, only so much of it need be present as is necessary to constitute a carrier for the staple leg clinching groove when a rotative clinching device is used, but where these disks are to feed or aid in feeding the material they should of course be continuous.
